ABSTRACT:
A mass spectrometer having an ionization source, a ion trap mass analyzer, an ion guide and gating apparatus between the ion guide and the ion trap. The gating apparatus includes sealing apparatus. A stream of ions from the ion source are guided to through the gating apparatus in pulses to the ion trap. The number of ions in each pulse are controlled by the scaling apparatus.
